Android: Viewpager inside a fragment of Navigation Drawer

Question

I'm currently developing an Android application what I need is to implement a Viewpager or Tabs inside a fragment of Navigation Drawer. I already implemented the Navigation Drawer from this tutorial: Navigation Drawer Tutorial

Now I have my Navigation Drawer consist of 3 fragments. Fragment A, Fragment B, Fragment C

on Fragment A how can I add a Viewpager for this Fragment?

This is definitely possible. You just need to use child fragments for the viewpager. Other than that the implementation is straightforward. Create a custom pager adapter, use the standard viewpager api

Extend FragmentPagerAdapter like so:

private class MyPagerAdapter extends FragmentPagerAdapter
{
    public MyPagerAdapter (FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int i) {
        switch (i) {
            case 0:
                return Fragment1;
            case 1:
                return Fragment2;

        }
    }

    @Override
    public int getCount() {
        return 2;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        switch (position) {
            case 0:
                return FRAGMENT_1_NAME;
            case 1:
                return FRAGMENT_2_NAME;



        }
    }

You'll need an layout with a viewpager of course, then just make sure to hook it up like this in Fragment A:

myPagerAdapter = new MyPagerAdapter(this.getChildFragmentManager());
myPager = (ViewPager) mRoot.findViewById(R.id.pager);
myPager.setAdapter(myPagerAdapter);

Note that you'll need to use the support library and support fragments unless your minimum SDK is 4.2 or higher, since the child fragments are API 17
